With temperatures in the European Alps rising twice as fast as the global average, there’s little hope of saving some of the world’s most famous glaciers without immediate and significant cuts in greenhouse gas emissions.

And there’s little doubt that the warming is caused by those emissions. Findings from a new study show the sudden onset of warming about 30 years ago. The study, led by researchers with the Byrd Polar Research Center at Ohio State, offers new and compelling evidence that the Italian Alps are warming at an unprecedented rate.

Swiss researchers taking a close look at the effect of global warming say that plants, birds and butterflies sprinted uphill by anywhere from eight to 42 meters between 2003 and 2010 — a significant shift in a very short time, according to the study published in the online journal Plos One. Other research has shown that, in general, European bird and butterfly communities have moved on average 37 and 114 kilometers to the north, respectively.

The world’s mountain regions are warming swiftly

Scientists say there’s an urgent need for more widespread data collection and observations from high elevations

By Bob Berwyn

A new scientific report from climate scientists says the world’s highest mountains may be warming much faster than than the global average — and faster than previously thought.

Most of all, the researchers said more monitoring and observations of mountain temperature patterns are needed to assess the high-elevation changes. Continue reading “The world’s mountain regions are warming swiftly”

Global warming is heating up Austria’s lakes

Waters expected to warm by up to degrees 3 degrees Celsius by mid-century

Austria’s famed alpine lakes are facing fundamental change as global temperatures continue to warm. The Alpine region as a whole warmed three times as fast as the global average between 1980 and 1999.

Projected increases in water temperatures will likely alter basic structure, function and water quality in famed lakes like the Mondsee, near Salzburg, according to Dr. Martin Dokulil, a retired researcher from the Institute for Limnology at the University of Innsbruck in Austria.

Dokulil analyzed long-term data records for air temperature and surface water temperatures dating back to the mid-1960s from the Austrian Hydrological Yearbooks. He projected temperature trends for nine large lakes, finding that lake surface temperatures are likely to rise by up to 3 degrees Celsius by 2050 as a direct result of climate change.

Can the Hockbärneckalm survive global warming?

Climate change threatens mountain agriculture in the Alps

LOWER AUSTRIA — Austria’s high alpine pastures, called Alms, are an important part of the country’s cultural tradition. For centuries, herders have driven cattle and sheep up and down the sides of the mountains following seasonal cycles of plant growth and snow melt.

The livestock grazing is managed mindfully to promote vegetation growth and biodiversity. It may be a difficult concept to grasp at first, but the rhythm of alpine grazing actually fosters biodiversity. Orchids, medicinal herbs and wildflowers thrive in the clearings and create lush green open patches in the landscape that are aesthetically pleasing.
